I've got a 2017 FZ10 and im looking to do a cat delete with stock silencer. I really just want more (louder) sound. I've removed stock silencer and it's a bit better, however, not enough. Question is, if i delete cat, will i have to flash the ecu? (Keep in mind i really dont care about gaining power as i only ride when time allows me too and funds are a bit low right now). Also, has anyone else just left the servo motor hooked up instead of getting a servo buddy? Does it create any issues?

If you remove the cat you should do a reflash. But you will still have a very loud, and obnoxious, sounding machine because noise control is done in the cat. Personally I don't understand why riders want a loud bike that annoys everyone. Once you put earplugs in, helmet on and get above 50 mph the engine clatter and wind noise will mostly mask the exhaust sound.

There are plenty of threads of people de-catting, some positive, some negative. Read up and make your decision.

Me neither. But not only that. Without a cat, the fuel smell is awful, and you need to wash your riding clothes after every ride. And yes, you're also polluting waaaaay more, so worth mentioning. He he. Oh, and no, with the bike that loud, it's really bothersome at higher rpm, even with earplugs and wind noise. Super annoying. My stock bike with the Graves slip-on is borderline loud; no need for more than a slip-on IMO.

OP, the OEM can is straight-thru. If you decat, it's stupid loud man. You really need an aftermarket muffler with a baffle to avoid being hassled by the law, your SO, and neighbors. Many owners have gone back to quieter systems; do some research. We have enough of that with Harleys. Ha ha. Good luck anyway.

Thanks for all the input. Its all good info. If I were to just invest into a slip on with the cat will it maybe change the tone at all or is there lttle to no difference. Also if i were to keep the stock can off and just by a tip (for a more finished look) would it be hurting anything internally on the bike.

The Graves slip-on on my bike made a dramatic difference from stock. It sounds incredible. Very deep, loud enough, and refined. At around 3K rpm, while just tooling around, it sounds like a muscle bike. Remember the stock can is straight-thru and not tapered at all, so from no can to any can is not going to make a difference in fueling. Many folks here have installed just tips; search for those threads. But they sound raspy to me, and I don't like that. The stock can doesn't have a nice sound to it either, at least to me. And doesn't look nice either. What I liked about mine (pictured below) is you can remove the decal before installation, and it looks OEM, since it doesn't have springs or a band, and has OEM fit and finish. That's exactly what I wanted. If I were you, since you might like a louder exhaust than mine, I'd probably buy the Yoshi Alpha (which comes with a baffle), remove the baffle, and it should sound very similar to mine, which is deep and refined. If you don't think it's loud enough, then you can add a decat pipe (or a smaller cat) and install the baffle and you should be good to go. Good luck.

I have the Yosh Alpha T and huge improvement over stock. A little louder but much more depth in tone and personality. I've not tried it with the battle which isn't needed imo. 10 min installation, typical Yosh quality.

As I mentioned, you only need the baffle if you decat. Stock would be too tame with the baffle indeed. I suggested that system because it comes with a baffle, so he doesn't have to get a different exhaust if he wants more noise. Mine is the most stock looking (without decal), but has no baffle, so didn't recommend it to him. Yoshi is the only other I'd have considered if Graves didn't exist, due to also having a proper bracket and clamp (bands and springs look cheap to me). All others have one or both.

You're absolutely correct. The FZ/MT-10 doesn't even sound nice that freaking loud and raspy IMO. But at least the volume would go down from stupid loud to obnoxiously loud with a baffle. Ha ha.

In my opinion, thats spot on, hence my purchasing the Leo Vince baffled decat, so I also purchased a baffle from Scorpion for the RP1-GP but all that consisted of was a piece of tube about 2-3 inches long. They reckoned that any longer robs the MT10 of power and this supposedly reduces the noise by 1.5-2db. I reckon they're full of shit as the audible difference is so hard to detect!The Leo makes a difference compared to the standard decat though.

joeysako: Hey guys! I bought my '17 FZ-10 a little over a week ago. Brand new with "0" miles. I am coming from an 09 R1 and I still ride an 07 Warrior. I do love my Yamahas First upgrade will be a 2wheeldyno ECU flash and not sure which pipe....Jan 17, 2019 5:11:51 GMT -7*

exuptoy: Hi guys, newbie here from the uk. Just felt I had to register as I have today fitted the Leo to my 2018 10. Awesome sound on it but still a little loud with my Scorpion RP1-GP. Hope you guys like it.Oct 29, 2018 12:27:57 GMT -7
